RIP TV, which had been featured at HOS 2001 and with a sequel in 2002, did not return. Instead, it was replaced by Eternal Reward.

All of the haunted houses from 2002 had returned to the event, excluding Bloody Bayou, which had been replaced by Darkheart's Fear Fair, and Escape From Insanity, which instead had the sequel Escape From Insanity: Resident's Revenge.
